Consider the Si structure shown in Figure Q2 at room
temperature.
(a) Sketch the built-in potential of the structure, from n+ region
on the left to n+ region on the right.
(b) Estimate the hole concentration at the center of the p-type
region.
(c) Sketch the energy band diagram across the structure, from n+
region on the left to n+ region on
the right.
( d) Calculate the capacitance of this structure at a bias voltage
of 0 V.
